Patent GB-673923-A (GB)
Title: Improvements in fluid control valve devices
IPC: F16K31/08
Filed: 1947-07-01
Abstract: 673,923. Valves. ETABLISSEMENTS MERLIN & GERIN, and LATOUR, A. July 1, 1947, No. 17280/47. Class 135 [Also in Group XXXV] In a valve device for controlling the flow of compressed fluid comprising electromagnetic means for opening the valve, the valve is maintained open by the action of either the combined effects of the electromagnetic means with reduced current and the impact of the fluid escaping through the valve orifice, or the sole effect of the impact of the escaping fluid when the reduced current has ceased. The valve 7, Fig. 1, is attracted downwards by a coil 2 when a switch 3 is depressed. A relay coil 5 is then energized to open a switch 6 so that current passes through a resistance 4, the reduced current, together with the impact of the fluid escaping through the valve orifice, then holding the valve open. In a modification, the initial opening current is obtained from a condenser, the reduced current then being the normal current supplied through a resistance. The coil 2, carried by the valve, may move between the poles of a permanent or electro-magnet, while the valve may comprise a cup loosely surrounding a nozzle in order to gain the full impact of the escaping fluid. As shown in Fig. 6, the valve is carried on a spring-loaded lever 42 actuated by an electro-magnet 45. The nozzle 48 carries a piston ring 49 sliding and controlling ports 47 in a cylinder 46 forming the valve, while a duct 55 through the end of the cylinder leads to a bellows 54 mounted on a ball joint 57. This arrangement allows of a tighter closing and a quicker opening of the valve. The bellows may be dispensed with, while the piston rod 39 of a piston 38 forming part of a pneumatic servomotor actuating a valve may be hollow so that air flowing out of it ejects air from the cylinder 37 through the nozzle and increases the impact on the valve.

Title: Polymerisation of unsaturated organic compounds
Inventor: COOPER WILFRED
IPC: C08F2/46
Filed: 1956-06-05
Abstract: Polymerizable unsaturated organic compounds are polymerized in aqueous dispersion by subjecting them to intermittent illumination. One or more photo-initiators may be present.  If more than one is used they should be sensitive to light in different sections of the spectrum.  The initiators may be of the kind that dissoci ate into free radicals or which produce free radicals by an electron transfer reaction.  Examples given are: 1-chloroanthraquinone, azo-bis-iso-butyronitrile, diacetyl, benzin, benzoin, anthraquinone, N-bromosuccinimide, di-chloramine, diazonium salts, e.g. salts of diazotized sulphanilic acid, iron salts, parabromo phenacyl bromide, uranyl nitrate and uranium dioxide.  Benzoin and uranyl nitrate may be used in combination.  The illumination periods may vary from 0.005 to 0.5 seconds while the dark periods are preferably not less than 0.2 seconds and in any event not less than twice the length of the light period.  The process may be effected using a central lamp and rotating reflector surrounded by a circle of transparent vessels holding the dispersion, or by circulating the dispersion through an illuminated chamber.  Emulsions, which are opaque, should be stirred to distribute the irradiated surface layer throughout the emulsion. Monomers referred to are vinyl ketones, e.g. vinyl methyl ketone, acrylate esters, e.g. methyl and ethyl acrylate, vinylidene chloride, vinyl chloride, vinyl acetate, methyl methacrylate, styrene and butadiene.  Copolymers may be prepared.  In Examples 1 to 4 aqueous emulsions of vinyl acetate are polymerized under various conditions and in Example 5 a mixture of butadiene and styrene.  The emulsions consisted of (1) vinyl acetate, sulphated methyl oleate and uranyl nitrate; (2) vinyl acetate, gum acacia and azo-bis-isobutyronitrile; (3) vinyl acetate, sulphated methyl oleate and azo-bis-isobutyrinitrile; (4) vinyl acetate, gum acadia and p-bromophenacyl bromide; (5) butadiene/styrene (70 : 30 by weight), tertiary dodecyl mercaptan, potassium oleate and uranyl nitrate.  The efficiency of the polymerization is compared with that using continuous illumination, efficiency being expressed as the ratio of polymerization rate to amount of light received.  Suspension polymerization is also referred to.

Title: Apparatus for preventing withdrawal without being metered, of quantities of liquid which are below the metering limit of liquid meters
IPC: G01F15/02
Filed: 1932-06-24
Abstract: 391,641. Rotary meters. BERGER, A., 2, Meineckestrasse, Breslau, Germany. June 24, 1932, No. 17849. [Class 110 (ii).] Apparatus for preventing the flow of liquid through a meter at a rate which is insufficient to permit of accurate measuring, comprises a valve beyond the meter which is operated by the pressures on its opposite sides ; damping means associated with this valve or an auxiliary valve are provided. The form shown in Fig. 2. which may be used in inverted position, if slightly modified, has a diaphragm 3 constituting the main valve separating the inlet 1 from the outlet 2, and provided with a small perforation 6 ; the pressure area of the upper surface is greater than that of the lower so that the valve is normally seated. An auxiliary valve 11 controls communication between the chamber 5 and a liquid-filled chamber 8 connected to the outlet 2 by a passage 23. When the pressure in the chamber 8 falls to a low value, that in the chamber 5 raises the valve 11 against the action of a pivoted loading member 12 carrying a damping plate 16 ; the pressure in the chamber 5 thus decreases, and the inlet pressure opens the valve 3. A byepass 17 is opened, when the valve 11 has performed part of its stroke. In other forms, the damping means comprise a dashpot member 25, Fig. 7, with or without grooves 27, 30 acting on the auxiliary valve 11, or a dashpot member 33, Fig. 9, acting on the main valve. In the form shown in Fig. 10, the spindle of the valve 11 contacts with a pivoted casing 40 containing a ball 39.

Filed: 1955-06-21
Abstract: 810,553. Hydraulic pit prop. GUTEHOFFNUNGSHUTTE STERKRADE A. G. June 21, 1955 [June 26, 1954], No. 17938/55. Class 20(2) A hydraulic pit prop having an upper prop part 3 slidable over a lower prop part 1 is provided with an energy accumulator which includes an air cushion 13 in which energy is stored during yielding of the prop under roof load, the pressure in the accumulator being subsequently applied, in order to reset the prop, first to a small area piston on the lower end of a piston rod 17 connected to and downwardly extending through the upper prop part 3 to rapidly extend the prop and then to a large area piston constituted by the upper end of the lower prop part 1 to put the prop under load. The yielding of the prop due to roof pressure causes liquid pressure medium to be displaced from a cylinder 16 containing the piston 17 and from a space 6 in the upper part 3 of the prop, through a rotary valve 10 into an extensible hollow body 12, which further compresses compressed air in the chamber 13 and increases the resistance of the prop. After a predetermined maximum pressure further yielding of the prop displaces liquid from the space 6 and cylinder 16 through a relief valve 14 into an overflow space 4. To remove the prop the valve 10 is rotated to a position, Fig. 4, in which the liquid in the space 6 and cylinder 16 is displaced directly into the space 4 whilst the prop is retracted under the influence of pressure liquid in the extensible hollow body 12 which acts constantly upon an annular piston face 15. To place the prop in a new position the valve 10 is rotated to a position, Fig. 1 (not shown) in which liquid under pressure of the compressed air in the accumulator chamber 13 flows from the hollow extensible body 12 into the cylinder 16 to rapidly extend the prop. Liquid from the space 4 is drawn by suction into the space 6 as it increases in volume. To apply working pressure the valve 10 is turned to a position, Fig. 3, in which the space 6, via the pipe 9, communicates with the hollow extensible body 12 so that the pressure therein is transmitted to the head plate 7 in the space 6. Filling inlets for liquids and compressed air are provided in the parts 7 and 5 respectively.

Abstract: 1,140,886. Counterbalancing material conveying members. FMC CORP. 25 April, 1966 [7 May, 1965], No. 17957/66. Headings B8B and B8E. A balancing mechanism for a material conveying conduit 24 vertically swingable about a riser pipe 14 comprises a lever 74 pivotally mounted on a bracket 28 adjustably fixed to the riser 14, a guide 26 connected to the conduit 24 and a spring arrangement urging the lever 74 against the guide 26 whereby downward movement of the conduit is counteracted. The guide 26 is fixed on the conduit by an adjustable bracket 22 and comprises a roller slideable along the surface 80a of a slot 80 in the lever 74. The latter is biased in the clockwise direction, Fig. 1, by a torsion spring which is attached at one end via a spring axle to the pivotal lever 74 and at the other end to the stationary bracket 28. The lever 74 and spring axle are coupled together by a pawl and ratchet mechanism through which the initial force at the torsion spring is adjusted. An adjustable spring 94 and buffer plate 92 in the remote end of the lever 74 cushions the guide pin assembly 26 when it reaches the end of its travel. The remote end 78 of the lever 74 is angled relative to the pivotal end such that during the last part of movement of the conduit 24 into its upper position, the force of the lever 74 is increased and automatically moves into its upper position. In a further embodiment, Fig. 6 (not shown), the lever (74) is not angled and so the conduit has to be manually moved into its upper position. Also the wall on one side of the slot in the lever is omitted.

Filed: 1931-09-29
Abstract: The manipulation of staple fibres comprising filaments of organic derivatives of cellulose is facilitated by applying to or incorporating in the materials a hygroscopic or deliquescent solid in an alcoholic medium.  Suitable hydroscopic or deliquescent solids are ammonium citrate, the chlorides of magnesium, calcium, zinc, iron and strontium; nitrates of magnesium, calcium, zinc, iron, cobalt and nickel; ammonium sodium and potassium acetates, formates, and phosphates; acetamide; methylamine hydrochloride; quaternary ammonium compounds and their salts.  Alcoholic bodies mentioned are methyl and ethyl alcohols, ethylene glycol, diethylene glycol, propylene glycol, and glycerine.  The composition applied may contain softeners, e.g. triacetin, ethylene glycol, and monomethyl-, monoethyl-, or diethyl-diethylene glycol, and also lubricants, such as oils and fatty acids.  The treatment is stated to avoid difficulties in spinning due to electrification of the fibres.  The hygroscopic solid in an alcoholic medium may be applied to the staple fibres, or to the filaments from which they are produced.  In the latter case, the solid may be applied to the filaments in the form of bobbins or hanks, or may be applied continuously to travelling filaments, as during a winding operation.  Again, the hygroscopic solid in an alcoholic medium may be incorporated in the spinning solution from which the filaments are produced.  Specifications 365,566, 365,621, 366,585, 387,004, and 388,768 are referred to.
